The bubblers are designed to ensure complete saturation of the bubbler gas by having a large surface area sintered glass frit located at the bottom of the bubbler to generate a large number of small bubbles to maximise the surface area of the gas exposed to the liquid. Additionally the elongated shape of the bubblers ensures that the transit time for the gas to be exposed to the liquid is maximised. 起泡器的设计是为了确保起泡器气体的完全饱和，通过在起泡器底部放置大表面积的烧结玻璃料来产生大量的小气泡，从而使起泡器的表面积最大化。气体暴露于液体中。此外，起泡器的细长形状确保了气体暴露于液体的传输时间最大化。
The shape also enhances turbulent mixing to enhance temperature uniformity of the liquid whilst ensuring the path length for thermal transfer from the surrounding oil layer is minimised. 该形状还增强了湍流混合，以提高液体的温度均匀性，同时确保从周围油层进行热传递的路径长度最小化。
